HEATING APPARATUS FOR RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 492,129, dated February 21, 1893.

Application filed August 28, 1885. Serial No. 176,531. (No model.)

To all whom it may concern:

Be it known that I, NAPOLEON W. WIL- LIAMES, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Heating Apparatus for Railways, of which the following is a specification.

My invention has reference to heating apparatus for trains and other vehicles; and it consists essentially in the combination of a circulating pump or vacuum device either located upon the locomotive car or vehicle and combined with a main supply pipe and a suction or return pipe, and suitable heating pipes or radiators in the cars or vehicles to be heated whereby preferably low pressure steam is caused to circulate through the radiators by the production of the partial vacuum or suction created in the return pipe, the various cars to be heated being coupled together in such a manner that the steam supply and suction pipes are made continuous; and in many details of construction all of which are fully set forth in the following specification and shown in the accompanying drawings which form part thereof.

In Letters Patent granted to me April 4, 1882, heating apparatus adapted to buildings and embodying substantially the same principle'is there described, and this application is intended to embody the same general principle only applied to moving vehicles such as railway trains, therefore in this application I do not claim the heating apparatus generically but only as applied to moving vehicles such as railway trains inwhich more than one car or truck are coupled together.

While I describe the use of a steam pump as a Vacuum creating device and employ the exhaust steam from the steam cylinder thereof as the steam which is caused to circulate in the heaters itis self evident that the steam might be drawn from the boiler in the form of live steam or might be drawn from the exhaust of the locomotive or even the exhaust of the Westinghouse compressor, though convenience would dictate that an auxiliary steam pump or a vacuum creating device should be used both for the production of the vacuum and supply of the heating steam.

A vacuum pump produces a tendency to create a vacuum, as it removes all air as well as steam and water from the system and maintains the constant circulation necessarily refor as soon as the condensed steam became hot the injector would stop working, and also a bubble of air would instantly stop the working of the injector, and much air necessarily finds its way into the mains hence an injector would not work satisfactorily or continuously, and a pump would consequently be required to maintain a constant and uniform partial vacuum. 7

In the drawings:Figure 1 is a side elevation of a portion of a railway train having my improvements applied thereto and, Fig. 2 is a plan view of the arrangement of the pipes and apparatus generally, showing the arrangement of the same upon the locomotive, tender and car.

F is the locomotive, B is the tender, and O is the car. All are supplied with steam supply pipe G and suction pipe H which may be coupled up as in the case of Westinghouse air brakes by flexible couplings h.

The car is provided with heating pipes L located under the seats in the usual Way one end of which is connected to the steam supply pipe G and the other end of which is connected to the suction pipe H. The admission or passage of steam through said heating pipes or radiators may be controlled by valves I.

The pipes G and H may be provided with stop valves M by which the circulation of steam through the radiating pipes may be controlled and the passage of steam through The locomotive is provided with a suction creating apparatus D which consists essentially of a steam pump, and the exhaust of the steam cylinder thereof is connected by a,

pipe E with the steam supplypipe G. Steam to this pipe G may be furnished from the boiler of the locomotive by pipe E having valve e. The vacuum creating cylinder or pump has its suction port connected by a pipe I with the suction pipe H and the condensed steam is forced by feed pipeJ through a check valvej into the boiler as feed water, or it desired the condensed steam may be forced through a pipe K having a valve 7;, into the water tank on the tender. It the valve 7.", is closed the feed water passes into the boiler.

N is a cold water pipe connecting the supply or water tank with the suction pipe 11 or I and is provided with a valve 02. hen this valve n is opened cold water is drawn into the suction pipes where it aids in the condensation of the steam creating a more positive vacuum and is forced in its heated condition by the pump either into the boiler or back into the tank raising the temperature of the feed water contained therein. It is evident that in locomotives in which the water tank is carried by the locomotive itself these pipes connecting with the water supply would be connected directlyand without the mediation of couplings.

0 represents the usual Vestinghouse air compressor and its exhaust may be connected by a pipe P with the suction pipe G supplying steam to the heating system as in the case of the exhaust from pump D.

R is the pipe provided with a valve 7' and connecting also with the steam supply pipe G and receiving steam from the exhaust nozzle S of the locomotive and would be used in cold weather when the supply of steam from the pump I) would not be sufficient. In the case of the locomotive or vehicle upon which the heating and circulating apparatus is supported, each end of the supply and suction pipes G and II is provided with valves g so that either end may be coupled to cars or vehicles and the other ends closed or both ends may be coupled to separate cars or vehicles.

Hot water might be circulated in this manner with or without admixture with steam and thus heat the cars or vehiclesin the same way. In practice much of the steam is condensed and circulates as water.

The essential feature of this invention consists in separate cars provided with steam heating coils or radiators connecting with steam supply and suction pipes, two or more of such cars being adapted to be coupled together and receive their supply of steam from a common source, combined with a vehicle upon which is located suitable vacuum creating devices adapted to draw a supply of steam and condensed vapor from the suction pipe, and a source of steam connecting with a supply pipe to furnish preferably low pressure to the system.
